Summary of the Invention

Problems to be Solved by the Invention

[0004] The slipper of Patent Document 1 has a configuration in which an arch-shaped belt part is provided inside the upper part. It has a sole part that fits according to the unevenness of the sole of the foot and a belt part provided inside the upper part, and is a slipper that three-dimensionally wraps the foot. However, since the belt part is provided inside the upper part, there is a problem that the belt part catches on the instep of the inserted foot when putting on or taking off the slipper, making it difficult to wear.

[0005] In this invention, both ends of the belt portion are provided on the outside of the upper portion, and the belt portion is passed through a slit in the middle of the upper portion, so that the belt portion is only provided in the central part of the inside of the upper portion. Therefore, when inserting the foot into the slipper, the belt portion does not get caught inside, allowing for smooth putting on and taking off. The belt portion is made of a stretchable material such as flat rubber, and it softly fits the instep of the foot, securing the foot inside the slipper. The slippers of this invention softly cradle the foot while walking, allowing for comfortable walking. [Means for solving the problem]

[0006] The slippers of this invention comprise a sole portion that supports the sole of the foot, an upper portion that extends from both ends of the sole portion and covers the instep of the foot, and a flat, plate-shaped belt portion made of a stretchable material that forms an arch into which the instep of the foot is inserted. The belt portion is characterized in that both ends are on the outer surface of the upper portion, and the central portion of the belt portion is provided on the inner surface of the upper portion, passing through a notch provided in the upper portion.

[0007] According to this design, the flat, stretchable belt portion securely fastens the instep of the foot, providing a comfortable fit and enabling comfortable walking. Furthermore, since both ends of the belt portion are on the outside of the upper portion, the belt portion does not catch on the instep when putting on the slippers, allowing for smooth insertion and removal of the feet, thus providing slippers that are easy to put on and take off.

[0008] Furthermore, the slippers of this invention are characterized in that both ends of the belt portion are in contact with the sole portion.

[0009] According to this design, since both ends of the belt portion are in contact with the sole portion, the belt portion can be securely attached to the entire instep of the foot, resulting in a slipper that fits snugly and wraps around the entire foot.

[0010] Furthermore, the slippers of this invention comprise a sole portion that supports the sole of the foot, an upper portion that extends from both ends of the sole portion and covers the instep of the foot, and a flat belt portion made of a stretchable material that forms an arch into which the instep of the foot is inserted, wherein both ends of the belt portion are sewn to the inner surface of the upper portion, and the arch formed by the belt portion is shorter than the arch formed by the upper portion.

[0011] According to this design, the flat, stretchable belt portion securely fastens the instep of the foot, providing a comfortable fit and enabling comfortable walking. Furthermore, since both ends of the belt portion are securely sewn to the inside of the upper portion, the belt portion does not catch on the instep when putting on the slippers, allowing for smooth insertion and removal of the feet, thus providing slippers that are easy to put on and take off.

[0012] Furthermore, the slippers of this invention are characterized in that both ends of the belt portion are in contact with the sole portion.

[0013] According to this design, since both ends of the belt portion are in contact with the sole portion, the belt portion can be securely attached to the entire instep of the foot, resulting in a slipper that fits snugly and wraps around the entire foot. [Brief explanation of the drawing]
